Banner Engineering ES-FA-9AA Interlock Safety Relay

The Banner ES-FA-9AA E-Stop/Rope Pull Interlock Safety Relay is a compact safety relay module designed to monitor a single E-stop, rope-pull, or interlock input and provide three normally open safety outputs for controlled machine shutdown. It operates from a 24 V AC/DC supply and features one safety input channel configurable as dual or single, with three normally open outputs rated at 6 A each and no auxiliary output. The unit uses a removable terminal block and occupies 22.5 mm of panel width, making it suitable for space‑conscious installations. Classified as part of Banner’s ES and GM Series E‑Stop and Guard Monitoring Safety Relays, the ES-FA-9AA includes self‑checking circuitry and offers auto or manual reset to ensure a verified safe state before restart. The safety inputs are compatible with positive-opening switches, such as E‑stop buttons or rope/cable pull devices, supporting common interlock configurations for guarding doors, gates, and access points in industrial equipment. This single‑channel safety monitoring solution consolidates E‑stop, rope pull, and interlock monitoring, enabling reliable safety control with industry‑standard performance.
